Hapstone Start CBN stones set

Hapstone Start CBN stones are designed for use in Hapstone sharpening systems and are ideal for sharpening knives made from any type of steel. The Hapstone Start CBN sharpening stone is a CBN plate with a working surface of 152x25 mm and a thickness of 3 mm, adhered to an aluminum blank measuring 160 mm by 3 mm, with beveled ends for secure fixation.

The abrasive layer includes CBN abrasive evenly distributed throughout the volume with high packing density and a narrow grit range. Thanks to the galvanic coating, very fast and aggressive metal removal is achieved. These stones work significantly faster than most other diamonds.
